George was late for class one day and copied down two math problems on the board, thinking they were homework. It took him several days to solve the problems, which were actually unsolvable equations presented as a challenge. When George solved them, his professor was amazed, as not even Einstein had been able to solve the problems that had stumped mathematicians for thousands of years. George solved them because, as an absent student, he was unaware they were supposed to be unsolvable.
